It is known that 2-anilino-3-cyanopyridines (DE-A 3 731 626) have fungicidal action. Their action, however, is unsatisfactory. N-Phenyl-N-pyridin-2-ylureas having herbicidal and plant growth-regulating action are also known (EP-A 401 168). However, no fungicidal action is described for them.

It has now surprisingly been found that 2-anilinopyridines of the formula I as in claim 1 have a potent action against pests, in particular fungi, in particular phytopathogenic fungi, in particular Botrytis cinerea.

The compounds of the general formula I are prepared, for example, as described in the following schemes:

The compounds of the formula I are obtained, for example, by reacting the pyridine-N-oxides 1a with the respective aniline derivatives 1b in the presence of alkyl- or arylsulfonyl chlorides, preferably tosyl chloride, in the presence of a basic catalyst such as eg. alkali metal hydroxides, preferably sodium hydroxide or potassium hydroxide. The acid-catalyzed hydrolysis of the N-tosylanilinopyridines 1c yields the anilinopyridines I (cf. eg.: Yu. V. Kurbatov, M.A. Solekhova, Khim. Getero. Soedin., 7 (1986) 936).

The precursors 1a are known in some cases. They are prepared by processes described in the literature (see eg. R. A. Abramovitch, Heterocyclic Compounds, Pyridine and its Derivatives Vol 14, Part 1-4, Ed: A. Weissberger, E. C. Taylor and literature cited there). ##STR3##

Alternatively to this, compounds of the formula I can be obtained by reacting halobenzenes 1d with 2-anilinopyridines 1e under the action of base. Suitable bases are, for example, alkali metal hydrides, eg. sodium hydride or potassium hydride, or alkali metal amides, eg. sodium amide or potassium amide. ##STR4##

In addition, compounds of the general formula I can be prepared by reacting anilines 1f with the pyridine derivatives 1g with or without addition of base (cf. eg. D. M. Bailey et al., J. Med. Chem., 14 (1971) 439). ##STR5##

A further variant consists in reacting the pyridines 1h with α-halo-α-phenylhydrazonoacetic acid esters Ii, preferably α-chloro-α-phenylhydrazonoacetic acid t-butyl ester. The hydrolysis of the resulting N-cyanoanilinopyridines 1j with addition of base yields the anilinopyridines I (R. Fusco et al. Gazz. chim. ital., 98 (1968) 511). ##STR6##

Compounds of the general formula 3 can be prepared, for example, by converting compounds of the general formula 1 where R¹ =CH₃ by known processes using oxidants such as eg. hydrogen peroxide or peracids, preferably m-chloroperbenzoic acid, in protic solvents, preferably acetic acid, or in aprotic solvents, eg. dichloromethane, into the N-oxides 2 which, by reaction with alkylcarboxylic anhydrides, eg. acetic anhydride, and subsequent basic hydrolysis of the acyl intermediate, afford the hydroxymethylene compound 3 (see eg. D. Bailey et al., J. Med. Chem., 14 (1971) 439). ##STR7##

Compounds of the general structure 4, where Hal is fluorine, chlorine, bromine or iodine, are accessible from the corresponding hydroxide compounds 3 by processes known from the literature (eg. Houben-Weyl, Methoden der Organischen Chemie (Methods of Organic Chemistry), 4th edition, volume 5/3 and 4, Halogen Compounds). ##STR8##

A possible preferred process in this case for preparing the halides (Cl, Br) 4a,b is the reaction of the hydroxymethylene compound 4 with suitable halogenating agents, eg. thionyl chloride or thionyl bromide or with halogen compounds of tri- or penta-valent phosphorus (eg. PBr₃, PCl₃) in the presence or absence of a proton acceptor in the presence of an inert solvent, eg. hydrocarbons such as petroleum ether, cyclohexane, benzene, toluene or xylene. The reaction is carried out at from -20° C. to the boiling point of the corresponding solvent, with or without catalyst. Suitable catalysts are, for example, DMF or tertiary amines such as triethylamine, N,N-dimethylaniline or piperidine.

For preparation of the fluorides 4c, the hydroxymethylene compounds 3 are reacted at room temperature with a fluorinating agent, eg. diethylaminosulfur trifluoride, in an inert solvent, eg. dichloromethane.

Compounds of the general structure 5, where alkyl-X is C₁ -C₆ -alkoxy (eg. --CH₂ --O--alkyl where alkyl is eg. methyl, ethyl or isopropyl) or C₁ -C₆ -alkylthio (eg. CH₂ --S--alkyl where alkyl is eg. methyl, ethyl or isopropyl), can be obtained by reacting the compounds 4 with an alcohol (eg. methanol, ethanol or isopropanol), preferably in an inert solvent or in an excess of the alcohol concerned which simultaneously serves as a diluent, in the presence of a base (eg. alkali metals, their hydroxides or hydrides) in a temperature range which is from -20° C. to the boiling point of the appropriate solvent. ##STR9##

Compounds of the general formula 6 can be prepared starting from the hydroxymethylene compounds 3 by generally known processes (see eg. Houben-Weyl, Methoden der Organischen Chemie (Methods of Organic Chemistry), 4th edition, E3, 265 ff).

The preferred process used is oxidation with dimethyl sulfoxide in the presence of suitable auxiliary reagents, eg. oxalyl chloride/triethylamine. Possible diluents are inert organic solvents, eg. hydrocarbons such as petroleum ether, cyclohexane, benzene or chlorinated hydrocarbons such as dichloromethane, chloroform or 1,2-dichloroethane, or ethers such as eg. diethyl ether, tetrahydrofuran or dioxane. The reaction is carried out in a range from -80° C. to 50° C., preferably -70° C. to -10° C. ##STR10##

The oxime ethers of the general formula 7 are accessible by processes known per se (see Houben-Weyl, Methoden der Organischen Chemie (Methods of Organic Chemistry), 4th edition, volume 10/4 p. 55 ff). The preferred process used is the reaction of the aldehydes of the general formula 6 with a hydroxylamine H₂ N--O--R⁵ or the corresponding hydrochloride (eg. H, methyl, ethyl, hydroxyethyl, haloethyl, benzyl or benzyl substituted by fluorine, chlorine or methyl, C₃ -C₄ -alkenyl, C₃ -C₄ -alkynyl or CH₂ Ph) in a suitable diluent and suitable auxiliary reagents. ##STR11##

Possible diluents are solvents such as chlorinated hydrocarbons, eg. dichloromethane, 1,2-dichloroethane or alcohols, such as eg. methanol, ethanol, isopropanol or nitriles such as acetonitrile, propionitrile and water. Possible reaction auxiliaries are inorganic and organic bases, eg. alkali metal hydroxides, such as eg. sodium hydroxide, or alkali metal alkoxides, such as eg. sodium methoxide or alkali metal carbonates such as eg. sodium carbonate and potassium carbonate, or tertiary amines: triethylamine. The reaction is carried out at from 0° C. to the boiling point of the diluent employed, preferably 20° C.-80° C.

Compounds of the general formula 8 (R⁶ eg. C₁ -C₆ -alkyl, preferably methyl, ethyl, propyl or C₃ -C₆ -cycloalkyl, eg. cyclopropyl, cyclopentyl, cyclohexyl or C₁ -C₂ -alkyl substituted by chlorine, hydroxyl, cyclopropyl or benzyl, or allyl, propargyl and also phenyl or phenyl substituted by fluorine, chlorine, methyl or trifluoromethyl) can be prepared by reacting a compound of the general formula 6 with a primary amine of the formula H₂ N--R⁶ in which R⁶ has the meanings described above, in an inert solvent, eg. hydrocarbons: petroleum ether or cyclohexane, preferably toluene, benzene or xylene, in the presence of a reaction auxiliary (eg. small amounts of inorganic or organic acids, eg. toluenesulfonic acid), at from 0° C. to the boiling point of the respective diluent preferably from 80° to 120° C. ##STR12##

Compounds of the general formula 9 can be prepared by hydrogenation of the compounds 8 with elemental hydrogen under normal pressure or with overpressure in the presence of a catalyst, eg. palladium-carbon or Raney nickel in an inert solvent, eg. ethyl acetate, tetrahydrofuran or dioxane at 10° C.-120° C, preferably 20° C.-60° C. (see eg. Houben-Weyl, Methoden der Organischen Chemie (Methods of Organic Chemistry), volume 11/1 p. 602 ff). ##STR13##

Compounds of the general formula 10 where R¹ =CN can be prepared from compounds of the general formula 7 where R⁵ =H (7a) by processes known per se (see eg. Houben-Weyl, Methoden der organischen Chemie (Methods of Organic Chemistry), 4th edition, volume E5, p. 1346), the aldoximes being reacted in the presence of a solvent (eg. acetonitrile or dichloromethane) with a dehydrating agent (eg. acetic anhydride, trichloromethyl chloroformate, trichloroacetyl chloride, SOCl₂, etc.) at -20° C.-50° C., preferably 0° C.-20° C. ##STR14##

Compounds of the general formula 1j can, on the one hand, be obtained as described above starting from 2,4-disubstituted pyridines 1h, by reaction with α-chloro-α-phenylhydrazonoacetates. Alternatively to this, the compounds can be obtained starting from compounds of the general formula 1 in which the substituents have the meanings described in claim 1 and R³ is hydrogen, by reaction with cyanogen bromide in an inert solvent, eg. diethyl ether, tetrahydrofuran, dimethylformamide or dimethyl sulfoxide, in the presence of an organic or inorganic base (see eg. S. Salman et al., Indian J. Chem., 27B (1988) 583). ##STR15##

Compounds of the general formula 12 (R⁹ eg. H, C₁ -C₆ -alkyl, (eg. methyl, ethyl or isopropyl) or C₁ -C₆ -haloalkyl (eg. trifluorometh or trichlorometh) can be prepared by processes known per se by reacting compounds of the general formula I in which R³ is H with a carboxylic acid derivative. For the preparation of compounds according to the invention, suitable carboxylic acid derivatives are eg. acid chlorides, acid anhydrides or orthocarboxylic acid esters. The acylation of the compounds of the general formula 1 where R³ =H can be carried out with or without solvents, it also being possible for the solvent (eg. pyridine) to be used simultaneously as acid acceptor. The acid acceptor used can also be the starting material itself, other organic bases (eg. triethylamine) or inorganic bases.

Solvents suitable for the acylation reaction are all customary solvents (eg. pyridine, dichloromethane, dioxane or tetrahydrofuran). ##STR16##

Compounds of the general formula 14, Hal being eg. chlorine or bromine, can be obtained by reacting the N-oxides 13 with phosphorus oxyhalides (halogen is eg. Cl or Br) in an inert solvent or preferably without solvent at from 20° C. to the boiling point of the respective solvent, preferably 70°-120°. (See eg. R. A. Abramovitch, E. M. Smith; Pyridine-1-oxides, in Heterocyclic Compounds, Pyridine and its Derivatives Vol 14, Part 2, pp. 1-261, Ed: A. Weissberger, E. C. Taylor). ##STR17##

Compounds of the general structure 15, where alkyl-X is C₁ -C₆ -alkoxy (eg. O-alkyl where alkyl is eg. methyl, ethyl or isopropyl) or C₁ -C₆ -alkylthio (eg. S-alkyl where alkyl is eg. methyl, ethyl or isopropyl), can be obtained by reacting the compounds 14 with an alcohol or a thiol of the general formula HX-alkyl where X=O or S and alkyl has the meanings described above, (eg. methanol, ethanol or isopropanol) preferably in an inert solvent or in an excess of the alcohol concerned, which is used simultaneously as a diluent, in the presence of a base (eg. alkali metals, their hydroxides or hydrides) in a range from -20° C. to the boiling point of the corresponding solvent. ##STR18##

The following examples illustrate the preparation of the novel compounds.

EXAMPLE 1 2-(N-Tosylsulfonyl)anilino-6-cyclopropyl-4-methylpyridine (compound No. 28)

a) 7.74 g (0.045 mol) of m-chloroperbenzoic acid in 125 ml of dichloromethane are added dropwise at room temperature (20° C.) to 5.7 g (0.041 mol) of 2-cyclopropyl-4-methylpyridine in 50 ml of dichloromethane. The mixture is left for 6 h at RT (room temperature), and 3 g of sodium sulfite are then added. After 1 h, the reaction mixture is washed first with saturated sodium carbonate solution and then with water. The wash solution is extracted with dichloromethane, and the organic phases are combined, dried and concentrated. 5.7 g (98%) of 2-cyclopropyl-4-methylpyridine-N-oxide remain as a slightly yellow oil.

The mixture is stirred at RT for 24 h, the phases are separated, and the aqueous phase is extracted with dichloromethane. The combined organic phases are dried over sodium sulfate and concentrated. The residual oil is purified by column chromatography (cyclohexane:ethyl acetate=2:1). 3.54 g (70%) of the title compound are obtained as a slightly yellow oil.

3.2 g (0.0085 mol) of 2-(N-p-toluenesulfonyl)anilino-6-cyclopropyl-4-methylpyridine are taken up in 150 ml of conc. HCl and heated under reflux for 8 h. The solution is then largely concentrated, added to water, neutralized with potassium carbonate and extracted with dichloromethane.

After removing the solvent by distillation, 1.64 g (91.8%) of the title compound remain.

EXAMPLE 3 2-(N-Acetyl)anilino-4,6-dimethylpyridine (compound No. 7)

0.51 g (0.005 mol) of acetic anhydride is added dropwise at RT to 1 g (0.005 mol) of 2-anilino-4,6-dimethylpyridine in 10 ml of glacial acetic acid. The mixture is additionally stirred for 1 h, poured onto water, rendered neutral with 10% NaOH and extracted with dichloromethane. The organic extracts are dried and concentrated. A light brown oil remains, which crystallizes at once (0.64 g; 53%).

The following compounds are suitable, for example, for use according to the claimed process for controlling pests.

The compounds of the formula I are suitable as fungicides.

The fungicidal compounds or the compositions containing them can be used, for example, in the form of directly sprayable solutions, powders, suspensions, also high percentage aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusting compositions, scattering compositions or granules by spraying, atomizing, dusting, scattering or watering. The application forms depend on the intended uses; they should in each case if possible guarantee the finest dispersion of the active compounds according to the invention.

Normally, the plants are sprayed or dusted with the active compounds or the seeds of the plants are treated with the active compounds.

The formulations are prepared in known manner, eg. by extending the active compound with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents as auxiliary solvents when water is used as a diluent. Suitable auxiliaries for this purpose are essentially: solvents such as aromatics (eg. xylene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. mineral oil fractions), alcohols (eg. methanol or butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine or dimethylformamide) and water; carriers such as ground natural minerals (eg. kaolins, clays, talc or chalk) and ground synthetic minerals (eg. highly disperse silicic acid or silicates); emulsifiers such as nonionic and anionic emulsifiers (eg. polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants such as lignin sulfite waste liquors and methylcellulose.

Suitable surface-active substances are the alkali metal, alkaline earth metal or ammonium salts of aromatic sulfonic acids, eg. lignosulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalenesulfonic acid, as well as of fatty acids, alkyl- and alkylarylsulfonates, alkyl, lauryl ether and fatty alcohol sulfates, and also salts of sulfated hexa-, hepta- and octadecanols, as well as of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and its derivatives with formaldehyde, condensation products of naphthalene or of naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octyl phenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenol or tributylphenyl polyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol-ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite waste liquors or methylcellulose.

Powder, scattering and dusting compositions can be prepared by mixing or joint grinding of the active substances with a solid carrier.

Granules, eg. coated, impregnated and homogeneous granules can be prepared by binding the active compounds to solid carriers. Solid carriers are mineral earths such as silica gel, silicic acids, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate and magnesium sulfate, magnesium oxide, ground plastics, fertilizers, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas and vegetable products, such as cereal meal, tree bark, wood and nutshell meal, cellulose powder or other solid carriers.

Examples of such preparations are:

The compounds of the formula I are distinguished by an outstanding activity against a broad spectrum of phytopathogenic fungi, in particular from the Ascomycetes and Basidiomycetes class. In some cases they are systemically active and can be employed as foliar and soil fungicides.

They are of particular importance for the control of a multiplicity of fungi on various crop plants such as wheat, rye, barley, oats, rice, maize, grass, cotton, soybean, coffee, sugar cane, grapes, fruit and decorative plants and vegetable plants such as cucumbers, beans and Cucurbitaceae, as well as on the seeds of these plants.

The compounds are applied by treating the fungi or the seeds, plants, materials or the soil to be protected from fungal attack with a fungicidally effective amount of the active compounds.

Application takes place before or after the infection of the materials, plants or seeds by the fungi.

The compounds I are specifically suitable for the control of the following plant diseases:

Erysiphe graminis (powdery mildew) in cereals,

Erysiphe cichoracearum and Sphaerotheca fuliginea on Cucurbitaceae,

The novel compounds can also be employed in the protection of materials (wood preservation), eg. against Paecilomyces variotii.

The fungicidal compositions in general contain from 0.1 to 95, preferably from 0.5 to 90, % by weight of active compound.

Depending on the type of effect desired, the application rates are from 0.02 to 3 kg of active compound per ha.

In the case of seed treatment, amounts of active compound from 0.001 to 50 g, preferably 0.01 to 10 g, per kilogram of seed are generally required.

The compositions according to the invention can also be present in the application form as fungicides together with other active compounds, or eg. with herbicides, insecticides, growth regulators, fungicides or alternatively with fertilizers.

Use Example 1 Activity against Botrytis cinerea on bell peppers

Slices of green bell peppers were sprayed until dripping wet with aqueous active compound preparation which contained 80% active compound and 20% emulsifier in the dry matter. 2 hours after the spray coating had dried on, the fruit slices were inoculated with a spore suspension of Botrytis cinerea which contained 1.7×10⁶ spores per ml of a 2% strength biomalt solution. The inoculated fruit slices were then incubated at 18° C. for 4 days in moist chambers. The assessment of the Botrytis development on the attacked fruit slices was then carried out visually.

The result shows that the active compound 532 when used as a 125 ppm active compound-containing spray liquor exhibits a better fungicidal action (5% attack of the fruit) than the known comparison active compounds A and B (90% attack of the fruit).
